Just found out about this cool free program, which helps prevent you from getting suckered into thinking that you’re on a site like ebay.com , when you’re really at identitytheft.com

SpoofStick is a simple browser extension that helps users detect spoofed (fake) websites. A spoofed website is typically made to look like a well known, branded site (like ebay.com or citibank.com ) with a slightly different or confusing URL. The attacker then tries to trick people into going to the spoofed site by sending out fake email messages or posting links in public places - hoping that some percentage of users won’t notice the incorrect URL and give away important information. This practice is sometimes known as “phishing".
